This uses the simple concept of pixelating a photograph when someone stands in front of the camera. The pixelation has different parameters in the computer that project different images. Although this is an interactive art and the computer does it instantly when a person stands in front, I think it would also be easy to do it manually on photoshop.

The has trash collected from streets of NYC. 4 mechanical mirrors are made of various materials and have the same behavior and interaction.Any person standing in front of one of these pieces is instantly reflected on its surface. The mechanical mirrors all have video cameras, motors and computers on board and produce a soothing sound as the viewer interacts with them.

This is a nice idea. I wish they were a little more elaborate on explaining how it is done. However, I am assuming it has the same concept of the other interactive arts where the results of projection are coded based on different parameters such as how hard the gun is triggered.

This is creepy yet very funny. This art projects a spot light on random people and follow them around. All the date is registered in the data. It also has sound beams which talk to the people being targeted. This is an interesting way to play a prank on random people in the hallway.

Kinetic Shadows is an engaging urban installation that shows the energy of Athens city life during the Olympics. The shadows change throughout the day as well as the pedestrian interaction. During the night, the shadows light up. Pedestrians interact with this changing shadows throughout the day as they escape to this piece of sculpture for some cool air.
